Sony Vaio E Series - Trying To Get F Keys Working For Backlight


I have a Sony laptop E series I just bought and it has an Nvidia 410M chip on it and I've tried many things to get the F keys to work for backlight and nothing works, but the nvidia-settings changes them...

I tried the nvidia-settings as a user and when I log out and back the settings are changed, so I guess I have to do this as root to keep the changes?

This is everything I've tried and can't get to work; http://pastebin.com/SRiunjtG

So maybe the F keys can be linked to the nvidia-settings to get them to work?

THANKS

Try Xmodmap

mine below maps unused f5 and f6 to brightnessdown and brightnessup on my laptop.

keycode 71 = XF86MonBrightnessDown NoSymbol XF86MonBrightnessDown
keycode 72 = XF86MonBrightnessUp NoSymbol XF86MonBrightnessUp

Drop it into a file called .Xmodmap in your home folder, reboot.

see https://wiki.archlinux.org/index.php/Xmodmap for a step by step.

Option "RegistryDwords" "EnableBrightnessControl=1" In xorg.conf seemed to help it so now I can use the /etc/acpi I listed in pastebin and it works...

But when I use the F keys the contrast seems to be off, it's not as nice as when I use nvidia-settings which does 'All Channels' and makes it look better...

So this what I use right now;

Is there any way to convert this so it changes all the channels when it adjusts?

nvidia-settings --assign GreenBrightness=0.1
nvidia-settings --assign RedBrightness=0.1
nvidia-settings --assign BlueBrightness=0.1

THANKS
